IMPLEMENT FOR WRITING.

Application filed March 23, 1922. Serial No. 546,067.

7 '0 all whom it may concern:

Be it known that I, WILLIAM F. KELLY, a citizen ofthe United States, and a resident of Greenwood. in the count-y of Leflore and State of Mississippi, have invented certain new and useful Improvements in Implements for lVriting, of which the following is a specification.

This invention relates to an implement for writing.

The object of the invention is to provide a writing implement in the form of a pencil having a heated marking element and adapted to be used for writing upon paper or the like.

It is also an object of the invention that the marking element of the pencil be adapted to form amark upon paper, or the like, without scratching and to be used for producing clear and legible writing.

It is a further object of the invention that the device be exceedingly simple in construction and inexpensive'to manufacture.

Other objects, and objects relating to details of construction, combination and ar rangement of parts will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawings, in which I Figure 1 is a view in side elevation of the pencil. constructed in accordance with the present invention.

Figure 2 is a vertical longitudinal sectional view of the same with the cap omitted,

Figure 3 is an enlarged vertical longitudinal sectional view of the pencil point and a portion of the associated barrel.

Figures 4, 5 and 6 are transverse sectional views taken substantially on the lines 4l-4. 5-5 and 66 of Figure 3, respectively.

Referring to the drawings more partic u larly, the pencil substantially consists in three members, namely: a barrel B, a cap C, and a head member P. The barrel B is cylindrical and may be made of any metal desired and with its one end closed as at 10, while adjacent its other end said barrel is formed with a bead 11. The member P is hollow and consists in a cylindrical portion and a conical portion 13. The conical por tion 13 is filled with asbestos or the like as indicated at 14;, and said asbestos is held within the portion 13 of the member P by shellac or the like as at 14. The pointed end of the conical portion 13 of member P has mounted therein a ball-point 15, said ball-point being insulated from the I member P by micaor the like as indicated at 16. The ball-point 15 is stationary and has suitably connected thereto a pair of wires 17 and 18. The wire 17 is connected at its other end to a contact ring 19 which is embedded in the shellac l4, and the wire 18 has its other end connected to a contact plate 20 which is likewise embedded in the shellac 14. The cylindrical portion 12 of the member P has its ends formed with a curved portion adapted to form an exterior bead 21, Figure 1, and also adapted to cooperate with the bead 11 of the barrel B and hold the member P to said barrel B.

lVithin the barrel B there is positioned a battery B which is adapted to freely slide within the barrel B. The forward end of the. battery B is provided with a pair of contact buttons 22 which are adapted to contact with the contact ring 19 and contact plate 20 when said battery B moves forwardly a predetermined degree. The cap C is of the usual construction of a cap for fountain pens, that is, cylindrical in shape and with its one end closed as shown. The cap C is adapted to receive the member P and also engage with the bead 21 for holding said cap upon the pencil, The cap C also should have attached thereto a spring finger 23 by which the penoil may be retained in a persons pocket.

In the use of the present device, the pencil should be carried inverted so that the battery B will be positioned with its contacts 22 in spaced relation with the contacts 19 and 20 as illustrated in the drawings, Figures 2 and 3. Upon bringing the pen so that the point P will be lowermost the battery B will be moved to a position so that its contact will contact with the ring 19 and plate 20 and therefore cause a current to pass through the ball 15. The ball 15 will be heated sufficiently so that when moved over paper or the like it will sear the paper and leave a clear mark. The ball 15 serves as a point for the pencil and it will not scratch when being drawn over paper. The pencil can be used to write quickly and in an etlicieut manner. The battery B should be of such capacity that the current passingtherefrom to the ball-point 15 will be sufficient to heat the ball-point 15 the proper degree.

While I have shown an described the preferred form of my invention, I wish it to be understood that I am aware of the fact that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from the spirit of the invention as indicated by the appended claims.

I claim x 1. A device of the character described, comprising a barrel, an electric storage battery positioned within said barrel, a metal writing point carried at the one end of said barrel adapted to be heated a predetermined degree with the passage of an electric current therethrough, and means whereby the battery will be automatically connected to cause a current to pass through said writing point when said barrel is elevated with respect to the writing point.

2. A device of the'character described, comprising a barrel, an electric storage battery positioned therein, a head member carried at one end of the barrel, a metal marking element carried at the end of said head member, and connecting means whereby the marking element may be heated a predetermined degree by said battery.

3. In a device of the character described, a barrel, an electric storage battery slidable therein, a head member carried upon one end of the barrel, said head member ta pering toward its free end and carrying a metal point in said free end, and means whereby when said barrel is raised to bring the head member lowermost, the battery will be connected with the metal marking point for heating the same a predetermined degree.

4:. In a device of the character described, a barrel, an electric storage battery slidable therein, a head member carried upon one end of the barrel, said head member tapering toward its free end and carrying a metal point in said free end, means whereby when said barrel is raised to bring the head member lowermost, the battery will be connected with the metal marking point for heating the same a predetermined degree, and a cap adapted to fit over said head member.

5. A device of the character described, comprising abarrel terminating at its one end in a point, a ball carried at the point of barrel, a partition within the barrel made of insulating material, a pair of contacts carried by the said partition, said contacts being each electrically connected to said ball, and a battery within said barrel adapted to cause a current to pass through said, ball.

6. A device of the character described, comprising a barrel terminating at its one end in a point, a ball carried at the point of barrel, a partition within the barrel made of insulating material, a pair of contacts carried by the said partition, said contacts being each electrically connected to said ball, and a battery within said barrel movable and adapted upon the barrel being tilted with its pointed end downward to move in position for connecting the said contacts and causing an electric current. to pass through said ball.

7. A device of the character described. comprising a storage battery. means surrounding the storage battery adapted to serve as a stem of a writing implement, a scoring point carried at the one end of the last named means, and connecting means between the storage battery and the scoring point whereby the scoring point may be heated to serve as a marking element.

8. In combination, a casing, a storage battery positioned therein, a scoring point or element carried at one end of the casing, and means whereby current from said storage battery may be" caused to heat said scoring element.

9. A device of the character described, comprising a barrel. an electric storage battery carried therein and slidable within said barrel, a scoring or writing element carried at one end of the barrel, and connecting and contact means whereby when the barrel is tilted the storage battery will be electrically connected for heatin said scoring element.
